Abstract (en)
[origin: US2021051398A1] A line array loudspeaker has a first group of acoustic drivers comprising a first plurality of acoustic drivers each comprising an axis, the first plurality of acoustic drivers arranged so that their axes are parallel. There is a second plurality of acoustic drivers each comprising an axis, the second plurality of acoustic drivers arranged so that their axes are parallel. The first and second plurality of acoustic drivers are arranged such that a projection onto an azimuth plane of the axes of the first plurality of acoustic drivers intersects with a projection onto the azimuth plane of the axes of the second plurality of acoustic drivers at a first, fixed articulation angle. There is a second group of acoustic drivers that is adjacent to the first group. The second group comprises a third plurality of acoustic drivers each comprising an axis. The drivers of the second group are arranged such that a projection onto the azimuth plane of the axes of the third plurality of acoustic drivers intersect at varied articulation angles.
